Detailed Product Description

    This product is used in AC 50Hz, 27.5kV electrify railway power network, it can frequently open and break and close rated current, overload current and rated short circuit current, can also be used in a complete set device of single-phase SP indoor HV vacuum breaker of condenser current, the circuit breaker of this breaker use is VT7~31.5/1250-25 single-phase SP vacuum circuit breaker.

    VT10~31.5/1250-25 type single-phase SP indoor HV vacuum circuit breaker formed by breaker handcart, current exchangeable ware, once separate breakpoint, handcart slide way, pushes on device with hand and branch or combined floodgate guidance panel, etc. In fact, it formed an open type distribution interval.

This complete set of device has the automatic control chest, can realize circuit breaker local control and remote control.

The device process the merits such as long life, convenient uses, simple maintain, not polluted and does not have dangerous of explode, etc. And is suitable in the harsh work condition of frequently operation.

    VT10~31.5/1250-25 type single-phase SP indoor HV vacuum circuit breaker adopt entire support method of console model, the vacuum extinguish arc room seals up in two basic insulation muffs pressed by the epoxy resin material, insulation muffs is used also as support, and gets rid of the influence that dustand humidity moisture to the insulation of arc, and raise the dustproofing resisted tide ability of circuit breaker, the outerinsulation distance is equal more than 820mm, it can satisfy the requirement of two grade filthy district insulation.

    Fitted with spring energy storage structure, and possessing the hand moves energy storage and motor-driven energy storage merit ability, the operation organization is putted in the front organization chest, among them including energy storage system, drive mechanism and sheds the knot ware and supplementary switch,VT7 circuit breaker united operation organization and arc room into whole, this kind of device can make conduces motive construct and the arc room opens closes ability more identical, reduces unnecessary the middle transmission link, reduces energy consumption and noise, makes the ability of circuit breaker more reliable.

    The breaker process the merits such as long life, convenient use simple maintain, no pollute and does not have dangerous of explodes, etc. and is suitable in harsh work condition of frequently operation.
